Mercedes-Benz automobiles are among the most cutting-edge on the market. Basically, this means that if anything goes wrong with your car, your car will be on top of it by coming up with fault codes. In the past, if anything went wrong with your car, a trained mechanic would rely almost entirely on guesswork to resolve the problem. This was a painstakingly long process that involved taking components apart, testing them individually, and putting them back together before testing another possibly faulty part. Nowadays, mechanics use scanners that plug into a modern vehicle to get fault code readings. A fault code is a series of letters and numbers that describe a very particular problem in a car. Fault codes differ from ordinary malfunction indicator lamps or MILs engine temperature, battery warning, oil pressure, brakes, etc. Each DTC will contain 5 characters with at least 1 letter, with the first character always being a letter. These letters refer specifically to hybrid propulsion systems. The final numbers refer to a specific component related to a faulty system.
